Pressure Test Radiator Cap Service & Cost

What is the radiator cap pressure test all about?

In a pressurized cooling system like those found on all cars, your car’s radiator cap is calibrated to seal in coolant to a particular pressure point, then allow some vapor to escape once that threshold has been reached. The ejected fluid is piped into the overflow bottle you might have seen in the engine bay. Then, as the engine cools, the coolant level may drop inside radiator. When that happens, a reverse-flow valve in the radiator cap opens to allow fluid from the bottle to return to the radiator. A radiator cap that isn’t working properly may cause too much fluid to escape the system.

Keep in mind:

A radiator cap pressure test is quick and simple, and replacement radiator caps are inexpensive.

Leaving a defective radiator cap in place can cause damage to the engine.

Heliodoro did a fantastic job. He showed up exactly on time (a couple minutes early actually) and was friendly, professional and courteous. He finished my brakes in just over an hour and I'm back on the road. I would absolutely book him for service again. Best part is I never even had to leave my house.
